Arkham-jester

Arkham is a scholar with supernatural abilities and knowledge about the demon world's folklore. He is taller than Dante and Vergil, bald to the extent of having no eyebrows, and has a scar covering the left side of his face, which is seen to pulsate in a few cutscenes. It is the result of a botched ritual to turn himself into a devil, in which he sacrificed his wife. Like his daughter Lady, he has Heterochromia. In most of Arkham's scenes he is holding a book, even in combat.
